v2025.03.0

Added

• Added a ManagedArray::clone function and deprecated chai::deepCopy.

Fixed

• Fixes reallocate when using pinned or unified memory.
• Adds missing synchronize when using pinned memory.
• Fixes possible hangs when evicting data.
• Now respects allocators passed to ManagedArray constructors when CHAI_DISABLE_RM=TRUE.

Removed

• Removes deprecated ManagedArray::getPointer method. Use ManagedArray::data instead.
• Removes ManagedArray::incr and ManagedArray::decr methods. Use ManagedArray::pick and ManagedArray::set instead.
• Removes optional support for implicitly casting between raw pointers and ManagedArrays (CHAI_ENABLE_IMPLICIT_CONVERSIONS). Use makeManagedArray and ManagedArray::data to perform explicit conversions instead.
• Removes equality and inequality comparison operators between ManagedArrays and raw pointers.
• Removes make_managed_from_factory function for creating managed_ptr objects from factory functions. This change will lead to safer adoption of allocators during construction and destruction of managed_ptr objects.
• Removes CHAI_ENABLE_PICK CMake option. ManagedArray::pick and ManagedArray::set will always be available.

Updated

• Updated to BLT v0.7.0
• Updated to Umpire v2025.03.0
• Updated to RAJA v2025.03.0

Full Changelog: v2024.07.0...v2025.03.0

Note: The tarball and v2025.03.0 tag were updated on Mar 20, 2025 at ~4 pm. If someone happened to obtain a version before then, they should grab a new version (which might necessitate deleting the v2025.03.0 tag locally in CHAI repositories and pulling the tag down again).

v2024.07.0

Changed

• Updated to Umpire v2024.07.0 and RAJA v2024.07.0
• Increased minimum CMake version required to 3.23
• Turns off benchmarks and examples by default
• Enable RAJA plugin by default

Full Changelog: v2024.02.2...v2024.07.0

v2024.02.2

What's Changed

• Replaced RAJA::loop_exec with RAJA::seq_exec
• Updated to RAJA v2024.02.2
• Improved debugging with GPU simulation mode

Full Changelog: v2024.02.1...v2024.02.2

v2024.02.1

What's Changed

• Update BLT to v0.6.2
• Update Umpire and RAJA to v2024.02.1
• CI updates

v2024.02.0

Added

• Support for APUs with a single memory space. To use, configure with -DCHAI_DISABLE_RM=ON -DCHAI_GPU_THIN_ALLOCATE=ON.

Changed

• Moved installed CMake targets from share/chai/cmake to lib/cmake/chai to be consistent with other libraries in the RAJA Portability Suite
• Improved dependency handling during the build of CHAI and when it is imported into another library/application
• Removed ArrayManager::enableDeviceSynchronization and ArrayManager::disableDeviceSynchronization. Instead, use the environment variables for device synchronization after all kernels (e.g. CUDA_LAUNCH_BLOCKING or HIP_LAUNCH_BLOCKING)

Fixed

• Use free instead of realloc when the size is 0 (fixes a warning from valgrind)
